Salary sacrifice pension contributions work by reducing your contractual salary in exchange for an equivalent employer pension contribution, which lowers the salary used to calculate both Income Tax and National Insurance -- unlike a standard "net pay" pension contribution, which reduces Income Tax but not National Insurance in the same way. On a £35,000 salary sacrificing 5% (£1,750 a year) into a pension: your salary for tax and NI purposes becomes £33,250. Taxable income after the £12,570 Personal Allowance is £20,680, all within the basic rate band, giving £4,136 Income Tax. National Insurance is 8% of £20,680 = £1,654.40. Total deductions of £5,790.40 leave £27,459.60 cash take-home pay a year, around £2,288.30 a month -- on top of this, £1,750 goes straight into your pension pot, and your employer may also add National Insurance savings from the arrangement, depending on their policy. Compare this to not sacrificing any salary: on the full £35,000 you would pay £4,486 Income Tax and £1,794.40 National Insurance, keeping £28,719.60 in cash but with no pension contribution -- so salary sacrifice costs you £1,260 in reduced cash take-home pay (£28,719.60 minus £27,459.60) in exchange for £1,750 landing in your pension, an effective saving of £490 (28%) compared with contributing the same amount from already-taxed income.
